IMPROVEMENT IN SCALE-BEAMS.

TO ALL WHOM IT MAY CONGERN;

Be it known that JOELv F. KEELER, in the city of Pittsburg, and State of Pennsylvania, have invented a new and useful Machine for Weighing the Stoel; to beput into Furnaces for Smelting Orcs, and also for other purposes; and I do hereby declare the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, like letters referring to like parts, in which- Figure 1 is a plan of one side (the graduated or managers side) of myhearn.

Figure 2 is a cross-section through the line A B.

Figure 3 is a cross-section through the line C D. A

Figure 4 is an enlarged front view of the movable poise d, showing the places g or g for labelling it, and the beam-branches lC to whiehAit-vis attached, and along which it is moved.

' Figure 5 is au enlarged cross-section ofthc salme, showing the labels or escutcheons g` and g', also the weights e e-added to the poise by the screwf, and also the handle fior moving the poises.

The nature of my invention consists in attaching, in any known way, a number oi'- morable poises, of any known form, to a. scale-beam, constructed in anyv known shape, providing stops of any known construction for' such poises, and labelling them in any knownway, and alsol for connecting the poises at will, in any known manner, with :i registering-device of any known construction.

To enable others skilled in the art to make and use my invention,I will proceed to describe its construction and operation. l

I construct my scale-beam in any known form, and of any known materials, or combinations thereof", and attach thereto pivots, loops, or clevises, balancing-weights, poises, and other appendages of weighing-scales; but. I usually prefer to make the beam' A with branches C, with movable poises d, and adjustable' stops In, each stop held to the place it is set at, o n its branch o'r elsewhere, by means of thc set-screw bi', or any other known device. When more convenient, I attach the stops to something else than a branch or part of the beam, as, for instance, to the framework or other. part of the scale, or t6 something else than the scale, in any known manner, so as to answr thev purpose or effect of graduating or determining the amount which the several poses shall each weigh.

The usual construction places the several branches, C, of the beam over each other, but I also construct and use the same horizontally to each other, as shown ata a. The graduated side ofthe beam is usually accessible only to the manager of the furnace, who sets the stops for thc several poises, so as to haye such proportions and amounts of each material, (used in making the iron, for instance,) weighed and put into the furnace, as he may desire. Each counterpoise, d, graduates the weight of the material which it balances or weighs, either by v the distance it traverses on its respective branch of the beam, or by the increase or diminution of its own weight, (by means of the weights e e, or other known deviee,),or else by changing both its weight and the distance for moving it on the beam. The counterpoises are moved along the beam by means of thc handle f, or

by any other known means; the shape of the counterpoise, of which the handle is a part, being imn'iatcrial.

The label, as atg or g', is usually attached to the poise, but is sometimes attached to the framework' of the scale, or to anything else contiguous to the poises, so as to designate to which poise each label belongs.

The beam herein shown is used either separately or in combination with a platform of any known construction, thus forming either a. simple or a compound-lever-platform scale, of any known shape or dimensions.

Having thus fully described the construction and use of my invention, what I claim, is- A poly-poised scale-beam, provided with adjustable or variable weights and stops, and constructed and operating substantially in the manner and for the purposes as described.
